    Like real numbers, the grouping does not affect the product or sum of 3 or more algebraic terms.
    Example:
    Sum:2x2+(4y+1)=(2x2+4y)+1,
    3x+(2xy+5y+2)=(3x+2xy)+(5y+2)=(3x+2xy+5y)+2.
    Product:3x*(2y*4xy)=(3x*2y)*4xy=3x*2y*4xy.
    Remember:
    Typically, same variable is grouped together in a single term and the product of same variable is expressed as power.
